What's the best EL84 amp?

Sorry- these are both integrateds! My only experience with EL84 monoblocks is with Heathkit UA-1’s. They get lots of good press, especially with ESL57’s. My experience was they need very efficient speakers to be OK. Despite Sheldon Stokes’ claims, they crapped out in an appropriately treated listening room.

Sorry for the duplicate reply just now. I also opted for a Rogue Atlas (with KT120’s) for my quads and nothing else I’ve tried has worked out so well. 
The best match for any EL84 amp in my direct experience is my Altec 604’s in 620 cabinets. 

@imintohifi have you tried the Rogue Atlas with your Altec's?  

Haven’t yet. I just got a 45 SET for them, replacing the Eico, and am swapping out different phono preamps to see how that sounds. The Eico at 14 watts was plenty powerful- it’s a fairly small 250 square foot space, with no carpet. Gets loud real fast. I bet the Rogue would sound great, but for this application it would blow the windows out. 2 high quality SET watts are great. The SET has volume pots- at 50 percent it’s as loud as I’d ever want to listen.

I don’t want to sell the Eico short- it’s really sweet. EL84 amps have treated me well.
